[0083] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of user equipment 11 and a plurality of access network equipment 12.

[0084] Among them, the user equipment 11 can be a device that provides voice and / or data connectivity to the user.

The user equipment 11 can be an Internet of Things user equipment, such as a sensor device, a mobile phone (or called a "cellular" phone) and a computer with an Internet of Things user equipment. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote user equipment (remote terminal), an access terminal, a user terminal, a user agent, a user device, or user equipment.

The network device may be used to convert received air frames into IP packets and serve as a router between the wireless terminal and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) network. The network device may also coordinate the attribute management of the air interface. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be the next generation system of the 5G system. The access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network).

[0086] Among them, the access network device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access network device 12 can also be an access device (gNB) adopting a centralized distributed architecture in a 5G system. When the access network device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access network device 12.

[0087] A wireless connection can be established between the access network device 12 and the user equipment 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0088] In some embodiments, E2E (End to End) or D2D (Device to Device) connections may be established between user devices 11. For example, in vehicle-to-everything (V2X) communication scenarios such as V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian).

[0089] In some embodiments, the wireless communication system may further include a core network device 13. A plurality of access network devices 12 are connected to the core network device 13 respectively.

[0090] In some embodiments, the core network device 13 may be a core network device in a wireless communication system. For example, the core network device 13 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the core network device may be a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS).

[0092] Among them, the AMF, PCF, SMF, etc. in the embodiments of the present disclosure may be implemented by a single physical device or by multiple physical devices. It is understandable that the AMF, PCF, SMF, etc. in the embodiments of the present disclosure may be a logical functional module within a physical device or a logical functional module composed of multiple physical devices, and the embodiments of the present disclosure are not limited thereto.

[0093] To facilitate understanding by those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, or can be implemented together with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies individually or in combination; the embodiments of the present disclosure do not limit this.

[0094] Services such as XR, cloud gaming, and video-based remote control of machines or drones are expected to contribute increasingly higher traffic to 5G networks. In addition to audio and video streams, XR services also involve multimodal data streams, such as data streams for biotactile perception. This multimodal data describes the same service or application, input from the same device or different devices (including sensors), and may be output to one or more destination devices. The various data streams in multimodal data often have certain, or even strong, correlations, such as the synchronization of audio and video streams, or the synchronization of touch and vision. These media services share common characteristics in their data streams, between the various data streams, and in the network transmission requirements of these service data streams. Effectively identifying and leveraging these characteristics will facilitate network and service transmission and control, as well as service assurance and user experience.

[0095] The 3rd Generation Partnership Project (3GPP) has defined a goal for XR (Extended Reality) and media services related to UE power management: studying potential enhancements to power management that take into account the traffic characteristics of media services; energy-saving enhancements, such as supporting the balance between device battery life and throughput / latency / reliability, and how to consider the traffic characteristics of XR-type services or media services to enhance CDRX (Connected Discontinuous Reception).

[0096] A key issue identified for 3GPP research on XR media services is that more efficient codecs require increased power consumption and higher reliability. Furthermore, higher throughput and lower latency budgets also require more power consumption and network resources. Therefore, a balance between Quality of Experience (QoE) and device power consumption needs to be considered. This key issue aims to address for XRM (Extended Reality Media) services: how to balance throughput, latency, and reliability with power consumption (e.g., device battery life).

[0097] Currently, there is no QoS policy mechanism to meet the above requirements. In particular, to support the transmission of XRM services and multimodal data streams, research is underway to explore potential enhancements to energy management that take into account the characteristics of XRM service traffic. For example, this could include balancing factors such as throughput, latency, and reliability while taking into account UE status information (e.g., device temperature, battery life, power supply mode, and CPU load).

[0098] FIG2 is a flow chart of an information processing method according to an exemplary embodiment. As shown in FIG2 , the information transmission method is performed by a PCF, and the method may include:

[0099] Step 201: Receive UE status information of UE;

[0100] Step 202: Determine the UE policy according to the UE status information.

[0101] The UE status information may be used to indicate the UE status. The UE status may include but is not limited to at least one of the following: UE battery status, UE power supply status, UE CPU load status, UE temperature status, UE power consumption status, etc.

[0102] The PCF may determine a policy for the UE according to the UE status information, for example, initially determining or updating QoS parameters of the service data flow of the UE.

[0103] In this embodiment, since the UE strategy is determined by the PCF based on the UE status information, the UE strategy determined in this way can reduce the waste of network resources and / or UE energy consumption caused by the inconsistency between the formulated strategy and the UE status, and can achieve a balance between UE energy consumption and service transmission performance (factors such as throughput, delay or reliability).

[0104] In one embodiment, as shown in FIG3 , the receiving UE status information of the UE includes:

[0105] Step 301: Receive UE status information of the user equipment sent by the AMF.

[0106] In some examples, the UE status information sent by the AMF to the PCF may be sent by the UE to the AMF via a non-access stratum (NAS) message, or may be sent by the UE to the RAN and then sent by the RAN to the AMF.

[0107] It is understandable that when the UE sends the UE status information to the AMF via a NAS message, the NAS message can be forwarded by the RAN, that is, the UE sends the UE status information to the RAN via a NAS message, and then the RAN forwards it to the AMF.

[0108] In one embodiment, the UE status information of the user equipment sent by the AMF includes at least one of the following:

[0109] Receiving the UE status information sent by the AMF based on the UE status information subscription request;

[0110] Receive the UE status information sent by the AMF based on subscription information or local policy.

[0111] In some examples, the UE status information subscription request is used to request the AMF to report the UE status information to the PCF when the subscription reporting conditions are met. Here, the UE status information subscription request can be sent by the PCF to the AMF.

[0112] PCF can obtain UE status information from AMF through subscription or other means.

[0113] In some examples, when a UE is in a migration scenario, after the PCF subscribes to UE status information from the old AMF, the subscription event is forwarded to the new AMF, and the new AMF triggers reporting. Here, the old AMF is the AMF with which the UE registered before registering with the new AMF. In other words, the old AMF is the AMF that registered one or more times before the UE's currently registered AMF.

[0114] In some examples, subscription information or local policy may be used to determine whether the AMF is allowed to send UE status information to the PCF. If the subscription information or local policy stipulates that the UE status information can be sent to the PCF, the AMF may send the UE status information to the PCF.

[0115] In one embodiment, the UE policy includes:

[0116] a policy for a guaranteed bit rate (GBR) data flow of the UE; and / or a policy for a non-guaranteed bit rate (Non-GBR) data flow of the UE.

[0117] Based on whether a lower limit guarantee for the transmission rate can be provided, service data flows can be divided into GBR data flows and non-GBR data flows.

[0118] GBR data stream is a data stream that provides the lowest transmission bit rate. Even when network resources are tight, the corresponding bit rate can be maintained.

[0119] Non-GBR data flows are data flows that do not provide a minimum transmission rate guarantee. In the case of network congestion, the service (or bearer) needs to withstand the requirement of reducing the rate.

[0120] In some examples, the PCF may update the policy of the UE's GBR data flow based on the UE status information, for example, by lowering or increasing the bandwidth control parameters of the UE's GBR data flow. The bandwidth control parameters may include a control parameter of the maximum uplink bandwidth and / or a control parameter of the maximum downlink bandwidth of the GBR data flow.

[0121] In some examples, the PCF may update the policy for the UE's non-GBR data flow based on the UE status information, for example, by lowering or increasing the bandwidth control parameters for the UE's non-GBR data flow. The bandwidth control parameters may include a control parameter for the maximum uplink bandwidth and / or a control parameter for the maximum downlink bandwidth of the non-GBR data flow.

[0122] In one embodiment, determining the UE policy according to the UE status information may include:

[0123] According to the status information of the UE, the policy of the UE is updated by updating QoS parameters.

[0124] Here, the QoS parameters may be for service data flows.

[0125] Different QoS parameters can be set for different UE states. For example, different QoS parameters can be set for different CPU loads. For example, for UEs with heavy CPU loads, the PCF's UE update policy can at least include reducing QoS parameters.

[0126] In one embodiment, the QoS parameter includes at least one of the following:

[0127] Maximum Flow Bit Rate (MFBR) of the GBR data stream;

[0128] The guaranteed flow bit rate (GFBR) of the GBR data flow;

[0129] The aggregated maximum bit rate (AMBR) of the Non-GBR data stream.

[0130] In some examples, the PCF may reduce or increase the MFBR of the uplink GBR data flow and / or the MFBR of the downlink GBR data flow based on the UE status information.

[0131] In some examples, the PCF may lower or increase the GFBR of the uplink GBR data flow and / or the GFBR of the downlink GBR data flow based on the UE status information.

[0132] In some examples, the PCF may lower or increase the AMBR of the uplink Non-GBR data flow and / or the AMBR of the downlink Non-GBR data flow based on the UE status information.

[0133] In one embodiment, the AMBR comprises at least one of the following:

[0134] User Equipment Aggregate Maximum Bit Rate (UE-AMBR);

[0135] Session Aggregate Maximum Bit Rate (Session-AMBR);

[0136] User Equipment Slice Maximum Bit Rate (UE-Slice-MBR).

[0137] In one embodiment, the method further comprises at least one of the following:

[0138] Sending the updated Session-AMBR to a Session Management Function (SMF), wherein the updated Session-AMBR is forwarded by the SMF to a User Plane Function (UPF);

[0139] Sending the updated Session-AMBR to the UE;

[0140] Sending the updated UE-AMBR to the RAN;

[0141] Sending the updated MFBR and / or GFBR to the UPF;

[0142] The updated UE-Slice-MBR is sent to the RAN, wherein the updated UE-Slice-MBR is applied by the RAN to all PDU sessions of the UE corresponding to the slice S-NSSAI (Network Slice Selection Assistance Information) with an activated user plane.

[0143] Specifically, if the PCF sends the uplink and / or downlink Session-AMBR to the SMF, it is forwarded to the UPF for execution. If the UPF receives the Session-AMBR value from the SMF, the UPF will enforce the uplink and / or downlink Session-AMBR updated by the PCF.

[0144] If the PCF sends a Session-AMBR to the UE, the UE executes the updated uplink Session-AMBR (if the UE receives a Session-AMBR, the UE will use the Session-AMBR to execute PDU session-based uplink rate limiting for the Non-GBR flow).

[0145] If the PCF updates the UE-AMBR, for Non-GBR QoS flows, the RAN enforces the UE-AMBR of each UE in the downlink and uplink for the Non-GBR QoS flows.

[0146] If the PCF updates the MFBR, the UPF enforces the updated downlink MFBR for the GBR QoS flow (MFBR is enforced in the UPF for the downlink of the GBR QoS flow). For the GBR QoS flow, the (R)AN enforces the updated uplink / downlink MFBR (MFBR is enforced in the (R)AN for both the downlink and uplink of the GBR QoS flow).

[0147] If the PCF updates the UE-Slice-MBR, then if the RAN receives the updated UE-Slice-MBR, the RAN will apply this UE-Slice-MBR to all PDU sessions of the UE corresponding to the S-NSSAI with an activated user plane.

[0148] In one embodiment, the UE status information is used to indicate at least one of the following:

[0149] The battery level of the UE;

[0150] The battery life cycle of the UE;

[0151] The power supply mode of the UE;

[0152] the CPU load of the UE;

[0153] The overheating state of the UE.

[0154] The battery level of the UE may be represented by a percentage of the remaining battery level. For example, the battery level may be divided into multiple battery levels from 0% to 100%, and different battery levels indicate different battery level ranges.

[0155] The battery life cycle of the UE may be represented by the battery usage time. The battery usage time of the UE may include at least one of the following: the usage time of the remaining battery power, the battery usage time, etc.

[0156] The UE power supply mode may be used to indicate the power supply of the UE. The UE power supply mode may include at least one of the following: battery power, external power supply (such as mains power), hybrid power supply (battery combined with mains power, etc.).

[0157] The UE's CPU load can be expressed as the average CPU load, which is the number of processes occupying the CPU (the number of processes currently being executed) and the number of processes waiting for CPU time (processes waiting for CPU time here refer to processes waiting to be awakened) within a CPU statistical cycle. The UE's overheat status is used to indicate whether the UE is overheating. For example, the UE's overheat status can be used to indicate whether at least one of the UE's central processing unit, the UE's power amplifier, the UE's wireless circuit, and the UE's battery is overheating.

[0158] For example, when the UE temperature is higher than a preset temperature value, the PCF can reduce the QoS parameters of the UE's service data flow, thereby reducing the energy consumption of the service data flow transmission, thereby reducing the UE temperature.

[0159] For example, when the UE battery power is higher than the preset power, PCF can improve the QoS parameters of the UE's business data flow, increase the transmission bandwidth, reduce the transmission delay, etc., thereby improving the user experience.

[0160] For another example, when the UE is overheated, the PCF can reduce the QoS parameters of the UE's service data flow, so that the UE reduces the processing volume of the service data flow and alleviates the UE overheating problem.

[0161] For another example, when the UE is powered by mains electricity and the UE temperature is low, the QoS parameters can be adjusted to increase the transmission bandwidth, reduce the transmission delay, etc., thereby improving the user experience.

[0162] In one embodiment, the service data flow of the UE includes at least one of the following:

[0163] XR service data flow of the UE;

[0164] The multimodal data service data flow of the UE.

[0165] XR service data flows typically require high bandwidth, low latency, and high reliability, resulting in significant UE energy consumption. XR service data flows are strongly correlated with the UE status indicated by the UE status information.

[0166] For example, XR service data streams will consume a large amount of UE battery power, causing the UE to require more power consumption.

[0167] Multimodal data service data flows are used to transmit data in different modes. They also require high bandwidth, low latency, and high reliability, resulting in significant UE energy consumption. Multimodal data service data flows are strongly correlated with the UE status indicated by UE status information.

[0168] In this embodiment, the PCF updates the QoS parameters of the UE's XR service data flow and / or multimodal data service data flow based on the UE status information, thereby achieving a balance between the transmission performance (throughput, delay or reliability and other factors) of the XR service data flow or multimodal data service data flow and the UE energy consumption.

[0169] FIG4 is a flowchart of an information processing method according to an exemplary embodiment. As shown in FIG4 , the information processing method is performed by the first AMF and includes:

[0170] Step 401: Send UE status information of the UE to the PCF; wherein the UE status information is used by the PCF to determine a policy for the UE.

[0171] The UE status information may be used to indicate the UE status.

[0172] The UE status may include but is not limited to at least one of the following: UE battery status, UE power supply status, UE CPU load status, UE temperature status, UE power consumption status, etc.

[0173] In this embodiment, by sending UE status information to PCF, PCF can determine the UE strategy based on the UE status information. The UE strategy determined in this way can reduce the waste of network resources and / or UE energy consumption caused by the mismatch between the formulated strategy and the UE status, and can achieve a balance between UE energy consumption and service transmission performance (factors such as throughput, delay or reliability).

[0174] In some examples, the UE status information is used by the PCF to update the UE's policy by updating QoS parameters.

[0175] In some examples, the UE's policy includes:

[0176] The policy of the GBR data flow of the UE; and / or the policy of the Non-GBR data flow of the UE.

[0177] Based on whether the lower limit of the absolute rate can be guaranteed, service data flows can be divided into GBR data flows and non-GBR data flows.

[0178] GBR data stream is a data stream that provides the lowest transmission bit rate. Even when network resources are tight, the corresponding bit rate can be maintained.

[0179] Non-GBR data flows are data flows that do not provide a minimum transmission rate guarantee. In the case of network congestion, the service (or bearer) needs to withstand the requirement of reducing the rate.

[0180] In one embodiment, the method further comprises:

[0181] receiving the UE status information sent by the UE through a non-access stratum (NAS) message;

[0182] and / or, receiving the UE status information sent by the RAN, wherein the UE status information is acquired by the RAN from the UE.

[0183] In some examples, the UE status information may be sent by the UE to the first AMF via a NAS message during the registration process.

[0184] In some examples, the UE status information may be sent by the RAN to the first AMF via NGAP (Next Generation Application Protocol, NGAP).

[0185] In one embodiment, the receiving the UE status information sent by the RAN includes at least one of the following:

[0186] receiving the UE status information carried by the RAN in a registration request; wherein the UE status information is carried in the registration request from the UE and / or the UE status information is sent to the RAN as an access node (AN) parameter;

[0187] receiving the UE status information sent by the RAN based on the UE status information request message of the first AMF;

[0188] The UE status information carried in a Radio Resource Control (RRC) message sent by the RAN is received.

[0189] In some examples, the registration request carries UE MM Core Network Capability information, where the UE MM Core Network Capability is, for example, UE 5G Mobile Management Core Network Capability, and the UE MM Core Network Capability information includes UE status information.

[0190] In some examples, the UE status information may be used as an AN parameter in an AN message. For example, during UE initial registration or mobile registration update, the UE status information is sent to the RAN as an AN parameter in an AN message.

[0191] The AN parameters include the UE status information, and may further include at least one of the following:

[0192] GUAMI (Globally Unique AMF Identifier), selected PLMN (Public Land Mobile Network) ID, requested NSSAI (Network Slice Selection Assistance Information) and establishment type, etc.

[0193] In some examples, the UE status information may be carried in a request response message that is used to respond to a UE status information request message from the first AMF. For example, if the AMF requires that the UE status information be used to set up or coordinate an XRM service or an XRM service group, the AMF may send a UE status information request message to the RAN.

[0194] In some examples, the UE status information may be carried in an RRC message, for example, the RRC message may be sent to the first AMF when the UE transitions from an RRC inactive state to an RRC connected state.

[0195] In one embodiment, the NAS message includes a registration request message.

[0196] In one embodiment, the UE status information is carried in the UE mobility management core network capability information in the registration request message.

[0197] In one embodiment, the sending the UE status information of the UE to the PCF includes:

[0198] Sending the UE status information to the PCF based on the UE status information subscription request;

[0199] And / or, based on subscription information or local policy, sending the UE status information to the PCF.

[0200] Exemplarily, the UE status information subscription request is used to request the AMF to report the UE status information to the PCF when the subscription reporting condition is met.

[0201] For example, the subscription information or local policy may be used to determine whether the AMF is allowed to send the UE status information to the PCF. If the subscription information or local policy stipulates that the UE status information can be sent to the PCF, the AMF may send the UE status information to the PCF.

[0202] In one embodiment, the sending the UE status information to the PCF based on the UE status information subscription request includes:

[0203] Sending the UE status information to the PCF based on the received UE status information subscription request sent by the PCF;

[0204] And / or, based on the received UE status information subscription request sent by the second AMF, sending the UE status information to the PCF.

[0205] Here, the UE status information subscription request can be sent by the PCF to the first AMF, or by the second AMF to the first AMF.

[0206] For example, in a UE migration scenario, after the PCF subscribes to the UE status information from the old AMF (i.e., the second AMF), the subscription event is forwarded to the new AMF (i.e., the first AMF), and the new AMF performs a trigger report. Here, the old AMF is the AMF registered before the UE registers with the new AMF.

[0207] In one embodiment, the sending the UE status information to the PCF based on the UE status information subscription request includes at least one of the following:

[0208] Based on the UE status information subscription request, upon receiving the UE status information, sending the UE status information to the PCF;

[0209] Based on the UE status information subscription request, when a reporting period is reached, sending the UE status information to the PCF;

[0210] Based on the UE status information subscription request, when there is a status value matching a reporting threshold in the UE status information, sending the UE status information to the PCF;

[0211] Based on the UE status information subscription request, when a reporting indication is received, the UE status information is sent to the PCF.

[0212] In some examples, the first AMF may send UE status information to the PCF based on the UE status information subscription request when the UE status information indicates a UE status change.

[0213] In some examples, the first AMF may compare each status value in the UE status information with the corresponding reporting threshold, and if there is a status value that reaches the reporting threshold, the UE status information is sent to the PCF.

[0214] For example, the reporting threshold corresponding to the battery power of the UE is 20%. When the UE status information indicates that the battery power of the UE is 15%, the first AMF sends the UE status information to the PCF.

[0215] In one embodiment, the UE status information is used to indicate at least one of the following:

[0216] The battery level of the UE;

[0217] The battery life cycle of the UE;

[0218] The power supply mode of the UE;

[0219] the CPU load of the UE;

[0220] The overheating state of the UE.

[0221] The battery level of the UE may be represented by a percentage of the remaining battery level. For example, the battery level may be divided into multiple battery levels from 0% to 100%, and different battery levels indicate different battery level ranges.

[0222] The battery life cycle of the UE may be represented by the battery usage time. The battery usage time of the UE may include at least one of the following: the usage time of the remaining battery power, the battery usage time, etc.

[0223] The UE power supply mode may be used to indicate the power supply of the UE. The UE power supply mode may include at least one of the following: battery power, external power supply (such as mains power), hybrid power supply (battery combined with mains power, etc.).

[0224] The CPU load of the UE can be expressed as the average CPU load, that is, the number of processes occupying the CPU (the number of processes already being executed) and the number of processes waiting for CPU time (the processes waiting for CPU time here refer to processes waiting to be awakened) within a CPU statistical cycle.

[0225] The overheat status of the UE is used to indicate whether the UE is overheated. For example, the overheat status of the UE can be used to indicate whether at least one of the central processor of the UE, the power amplifier of the UE, the wireless circuit of the UE, and the battery of the UE is overheated.

[0226] In one embodiment, the UE status information is used by the PCF to update the UE policy by updating QoS parameters.

[0227] For example, the UE status information is used by the PCF to reduce or increase the bandwidth control parameters of the UE's service data flow. The bandwidth control parameters may include control parameters of the maximum uplink bandwidth and / or control parameters of the maximum downlink bandwidth of the service data flow.

[0228] In one embodiment, the QoS parameter includes at least one of the following:

[0229] The MFBR of the GBR data stream;

[0230] the GFBR of the GBR data stream;

[0231] The AMBR of the Non-GBR data stream.

[0232] Exemplarily, the UE status information is used by the PCF to reduce or increase the MFBR of the uplink GBR data flow and / or the MFBR of the downlink GBR data flow.

[0233] Exemplarily, the UE status information is used by the PCF to reduce or increase the GFBR of the uplink GBR data flow and / or the GFBR of the downlink GBR data flow.

[0234] Exemplarily, the UE status information is used by the PCF to reduce or increase the AMBR of the uplink Non-GBR data flow and / or the AMBR of the downlink Non-GBR data flow.

[0235] In one embodiment, the AMBR comprises at least one of the following:

[0236] UE-AMBR;

[0237] Session-AMBR;

[0238] UE-Slice-MBR.

[0239] In one embodiment, the service data flow of the UE includes at least one of the following:

[0240] Extended reality (XR) service data stream of the UE;

[0241] The multimodal data service data flow of the UE.

[0242] XR service data flow of the UE;

[0243] The multimodal data service data flow of the UE.

[0244] XR service data flows typically require high bandwidth, low latency, and high reliability, resulting in significant UE energy consumption. XR service data flows are strongly correlated with the UE status indicated by the UE status information.

[0245] For example, XR service data streams will consume a large amount of UE battery power, causing the UE to require more power consumption.

[0246] Multimodal data service data flows are used to transmit data in different modes. They also require high bandwidth, low latency, and high reliability, resulting in significant UE energy consumption. Multimodal data service data flows are strongly correlated with the UE status indicated by UE status information.

[0247] In this embodiment, the UE status information of the UE is sent to the PCF through the first AMF, so that the PCF can update the QoS parameters of the UE's XR-type service data flow and / or multimodal data service data flow according to the UE status information, thereby achieving a balance between the transmission performance (throughput, delay or reliability and other factors) of the XR-type service data flow or multimodal data service data flow and the UE energy consumption.

[0369] Through NAS messages, UE status information (e.g., UE battery level, UE battery life cycle, UE power supply mode (including battery power or mains power / wall power), UE CPU load, UE overheating status) is sent to AMF (e.g., as one of the 5GMM Core Network Capabilities) during the UE registration process, and is sent to PCF via AMF; PCF performs QoS updates on UE and / or UE sessions and / or UE service data flows based on the UE status information (e.g., performs QoS updates on all or part of the XRM service data flows, or PDU sessions of the XRM service).

[0370] For the specific transmission and update processing of related network functions (NF), please refer to the following steps.

[0371] Step 701: The UE sends a registration request message to the (R)AN. The registration request carries the UE 5GMM Core Network Capability. The UE 5GMM Core Network Capability includes the capability support of the UE status information.

[0372] The AN message sent by the UE to the (R)AN may include: AN parameters, registration request (registration type, SUCI or 5G-GUTI or PEI, [last visited TAI (if available)], security parameters, [requested NSSAI], [mapping of requested NSSAI], [default configured NSSAI indication], [UE air interface capability update], [UE mobility management core network capability], ...).

[0373] If the UE supports providing UE status information, the UE carries the UE status information in the registration request.

[0374] To ensure that the UE MM core network capability information stored in the AMF is up to date, the UE shall send a NAS message carrying the UE MM core network capability information to the AMF during the initial registration and mobility registration update procedures.

[0375] Step 703: The (R)AN selects the corresponding AMF and forwards the UE's registration request to the AMF. The N2 message carries the registration request information from step 701. The AMF stores the UE status information. Specifically, the AMF stores the corresponding UE MM Core Network Capability containing the UE status information in the UE context.

[0376] The AMF checks the event subscription (and / or combines the subscription data and local policy) to confirm whether to perform the subscription event reporting. For example, if the UE status update implementation is subscribed, it confirms whether the subscription reporting conditions are met (for example, UE status change, various thresholds are reached, or power supply mode matches or changes, or immediate reporting is received, or periodic reporting, etc.), and performs notification reporting according to the subscription and reporting requirements. Alternatively, the AMF combines the subscription data and / or operator policy to confirm whether to send the UE status information to the PCF.

[0377] The N2 message sent by the (R)AN to the new AMF (New AMF) may include: N2 parameters and registration request (as shown in step 701).

[0378] The AMF shall always store the latest UE MM Core Network Capability received from the UE. When the UE provides UE MM Core Network Capability using registration signalling, any UE MM Core Network Capability received by the AMF from the old AMF / MME shall be replaced.

[0379] Step 716: Optionally, the new AMF performs AM Policy Association establishment / modification. If the operator policy or subscription information contains a UE status information provision requirement, the AMF provides the UE status information to the PCF.

[0380] Or if the PCF subscribes to the UE status information from the AMF, the AMF will trigger the report according to the reporting conditions of the subscription event (for example, UE status change, various thresholds reached, or power supply mode matching or change, or immediate reporting or periodic reporting received, etc.), and transmit the UE status information to the PCF.

[0381] Step 721b: Optionally, the new AMF performs UE policy association establishment.

[0382] The new AMF sends an Npcf_UEPolicyControl Create Request to the PCF. The PCF sends an Npcf_UEPolicyControl Create Response to the new AMF.

[0383] Optionally, the AMF may transmit the same UE status information as in step 716 to the PCF in this step.

[0384] If the operator policy or subscription information contains a requirement for providing UE status information, the AMF provides the UE status information to the PCF.

[0385] Alternatively, if the PCF subscribes to the UE status information from the AMF, the AMF will trigger the report based on the reporting conditions of the subscription event (for example, UE status change, various thresholds reached, or power supply mode matching or change, or immediate report received, or periodic report, etc.). If this is a UE migration scenario, after the PCF subscribes to the old AMF, the subscription event is forwarded to the new AMF, and the new AMF performs the trigger report. Here, the old AMF is the AMF registered before the UE registers with the new AMF.

[0386] Optionally, the PCF may perform UE-related policy updates based on the received UE status information. The PCF triggers the UE configuration update process and sends the updated UE-related policies (e.g., QoS updates) to the AMF and UE. Alternatively, when the PCF subscribes to the AMF, the PCF triggers the session modification process and sends the updated session-related policies to the SMF (UPF), RAN, and UE.

[0387] Specifically, the PCF combines the UE status information to update the QoS bandwidth parameters of the corresponding UE's service session / service data flow (for example, XRM service or multimodal data), including: 1) MFBR and GFBR of GBR flow, 2) AMBR of Non-GBR flow; specifically, it may include uplink and / or downlink GBR / Non-GBR data flow.

[0388] Among them, the GFBR update is performed on the GBR data stream, including lowering or increasing the GFBR; and the relevant AMBR update is performed on the Non-GBR data stream, including lowering or increasing the AMBR.

[0389] There are three different levels of AMBR update: UE-AMBR, Session-AMBR, and UE-Slice-MBR. UE-Slice-MBR update includes UE-Slice-MBR update for GBR data flows and UE-Slice-MBR update for Non-GBR data flows.

[0390] Based on UE status information, for example, if the current UE temperature is too high to meet the current bandwidth requirement, the PCF reduces the Session-AMBR of the XRM service and specifically performs the following QoS update.

[0391] If the uplink and / or downlink Session-AMBR is sent to the SMF, it is forwarded to the UPF for execution. If the UPF receives the Session-AMBR value from the SMF, the UPF will enforce the uplink and / or downlink Session-AMBR updated by the PCF.

[0392] If the Session-AMBR is sent to the UE, the UE executes the updated uplink Session-AMBR (if the UE receives the Session-AMBR, the UE will use the Session-AMBR to execute PDU session-based uplink rate limiting for the Non-GBR flow).

[0393] If the PCF updates the UE-AMBR, for Non-GBR QoS flows, the (R)AN shall enforce the UE-AMBR of each UE in downlink and uplink for Non-GBR QoS flows.

[0394] If the PCF updates the MFBR, the UPF enforces the updated downlink MFBR for GBR QoS flows (MFBR is enforced in the UPF for the downlink of the GBR QoS flow). For GBR QoS flows, the (R)AN enforces the updated uplink and downlink MFBR (MFBR is enforced in the (R)AN for both the downlink and uplink of the GBR QoS flow).

[0395] If the PCF updates the UE-Slice-MBR, then if the RAN receives the updated UE-Slice-MBR, the RAN will apply this UE-Slice-MBR to all PDU sessions of the UE corresponding to the S-NSSAI with an activated user plane.

[0396] 1) Whenever a request to establish or modify a GBR QoS flow is received, RAN admission control shall ensure that the sum of the GFBR values ​​of the admitted GBR QoS flows does not exceed the UE-Slice-MBR, and if a QoS flow cannot be admitted, RAN shall reject the establishment / modification of the QoS flow.

[0397] 2) The RAN shall ensure that the aggregate bit rate of all GBR and non-GBR QoS flows belonging to a PDU Session does not exceed the UE-Slice-MBR, while always guaranteeing the GFBR of each GBR QoS flow of the PDU Session.

[0398] Example 2

[0399] The UE sends UE status information to the NG-RAN via NGAP messages.

[0400] The main difference between Example 2 and Example 1 is that the method by which the PCF obtains UE status information from the AMF is different. In Example 1, the UE sends the information to the AMF via a NAS message, which is then transmitted to the PCF. In Example 2, the RAN obtains the UE status information from the UE and sends it to the AMF, which is then transmitted to the PCF.

[0401] As shown in Figure 8, the specific steps include:

[0402] Step 801: In the UE registration process, the UE sends a registration request message to the (R)AN, and the UE sends the UE status information (for example, UE battery level, UE battery life cycle, UE power supply mode (including battery power or mains power / wall power), UE CPU load, UE overheating status) to the NG-RAN; wherein, the UE status information is transmitted to the NG-RAN as an AN parameter of the AN message. Alternatively, the UE status information is simultaneously transmitted to the NG-RAN as a parameter in the registration request and directly forwarded to the AMF; or after the NG-RAN receives the UE status information in the AN parameter, it combines the operator policy or network configuration (for example, UE status information notification, or XRM service (or service group) function support) and carries the received UE status information in the registration request to the AMF. The NG-RAN stores the received UE status information.

[0403] For example, the AN message sent by the UE to the (R)AN may include: AN parameters (UE status information, such as UE battery level, UE battery life, UE power supply mode (including battery power or mains / wall power), UE CPU load, UE overheating status, etc.), registration request (registration type, SUCI 5G-GUTI or PEI, [last visited TAI (if available)], security parameters, [requested NSSAI], [requested NSSAI mapping], [default configured NSSAI indication], [UE air interface capability update], [UE mobility management core network capability], ...).

[0404] For another example, UE to (R)AN: AN message (AN parameters, Registration Request (registration type, SUCI or 5G-GUTI or PEI, [last visited TAI (if available)], security parameters, [requested NSSAI], [mapping of requested NSSAI], [default configured NSSAI indication], [UE radio capability update], [UE MM core network capability], [UE status information, such as UE battery level, UE battery life, power supply mode (including battery power or mains / wall power), UE overheat status], ...).

[0405] Step 802: The NG-RAN stores the received UE status information and selects the AMF to perform the UE registration process according to the AMF selection policy.

[0406] Step 803, step 816 and step 821 can refer to Example 1 and will not be described again here.

[0407] The remaining steps can be performed with reference to the registration process of the prior art.

[0408] After acquisition, AMF sends the UE status information to PCF according to the same sending method as in Example 1, that is, the way in which AMF sends it to PCF may include: 1) PCF sends a UE status information subscription request to AMF, and AMF reports to PCF after meeting the reporting conditions (reporting conditions, for example, receiving UE status information subscription report, periodic reporting, reaching a certain reporting threshold of relevant status information, or receiving an immediate reporting indication report); 2) or AMF decides that it needs to be sent and actively sends it to PCF based on the contract information or operator policy.

[0409] For a detailed description of PCF performing QoS update, please refer to Example 1, which will not be repeated here.

[0410] In addition, the AMF obtains UE status information from the RAN, and can also be obtained through the application scenarios of Example 3 and Example 4.

[0411] Example 3

[0412] If the AMF requires UE status information to be used to set up or coordinate an XRM service or XRM service group, the AMF may send a UE status information request message to the NG-RAN. This procedure is typically used during the registration procedure or when the AMF does not receive status information or XRM service indicators (e.g. as part of a 5GMM context).

[0413] As shown in Figure 9, the specific steps include:

[0414] Step 901: The AMF indicates whether it wants to receive UE status information and / or XRM service (or service group) indicator. The AMF may have the UE status information previously received by the AMF from the NG-RAN.

[0415] Step 902: After receiving the UE status information request message, the NG-RAN requests the UE to upload the UE status information, or requests the UE status information when there is no valid UE status information locally.

[0416] Step 903: The UE provides the NG-RAN with the UE status information for which it sends the RRC message.

[0417] Step 904: NG-RAN stores the UE status information. NG-RAN checks whether the UE status information is compatible with the operator's policy (eg, network configuration) to support XRM services.

[0418] To determine the appropriate UE status information response, operators can configure the NG-RAN to check whether the UE supports certain capabilities required for XRM services. In a shared network, the NG-RAN maintains a separate configuration for each PLMN.

[0419] The NG-RAN provides the AMF with UE status information and / or XRM service (or service group) indicators to indicate whether the UE status information (or UE capabilities, if status information is included as part of capabilities) and the operator policy are compatible and support the XRM service (e.g., suitable for power consumption requirements).

[0420] The AMF stores the received UE status information and / or XRM service (or service group) indicator (e.g. in the 5GMM context). The UE status information can be used as input for setting up the XRM service.

[0421] Step 905: If the NG-RAN requests UE status information from the UE in steps 902 and 903, the NG-RAN also sends the UE status information to the AMF. The AMF stores the UE status information and / or the XRM service (or service group) indicator.

[0422] Example 4

[0423] Connection recovery triggered by UE during RRC inactivity (can provide UE status information)

[0424] The UE uses the connection recovery procedure to perform a transition from the RRC Inactive state to the RRC Connected state.

[0425] As shown in Figure 10, the specific steps include:

[0426] Step 1001: UE to NG-RAN: RRC message (Resume ID). The UE initiates a transition from the RRC Inactive state to the RRC Connected state. The UE provides the Resume ID required by the NG-RAN to access the context stored in the UE.

[0427] The UE provides the UE status information required by the NG-RAN, which can be used to check operator policies or network configuration (e.g. XRM service / service group support).

[0428] Step 1002: The NG-RAN stores the received UE status information.

[0429] NG-RAN performs UE context retrieval. UE context retrieval is performed when the UE context associated with the UE attempting to resume its connection is not available locally on the accessed NG-RAN.

[0430] Step 1003: N2 path switching procedure: If the accessed NG-RAN node is able to retrieve the UE context, the accessed NG-RAN node initiates the N2 path switching procedure.

[0431] If the AMF requests N2 notification from the NG-RAN, the NG-RAN sends a UE notification message to report that the UE is in the RRC connected state.

[0432] If UE status information notification is requested, the NG-RAN provides the received UE status information to the AMF.

[0433] Step 1004: NG-RAN to UE: RRC message. The NG-RAN confirms to the UE that the UE has entered the RRC Connected state.

[0434] The information processing method provided in the present disclosure supports a balance between throughput / delay / reliability and power consumption (for example, policy determination and execution can be performed based on UE status information) by providing UE status information (such as UE battery level, UE battery life, power supply mode including battery power or mains / wall power, UE overheating status) to the PCF.
